PRINTING ATTACHMENT FOR PAPER-BAG MACHINES.

SPECIFICATION forming part of Letters Patent No. 140,380, dated November 11, 1890. Application filed July 21, 1888. Serial No. 280,629. (No model.)

To coZZ whom it may concern.-

Be it known that I, THEODORE R. TROENDLE, a citizen of the United States, residing at Batavia, Kane county, Illinois, have invented certain new and useful Improvements in Printing Attachments for Paper-Bag Machinery, of which the following is a specification.

The object of my invention is to provide machinery which is so connected and adapted to a paper-bag machine that it will imprint on the web of paper out of which the bags are formed desired matter at regular intervals and as a part of one continuous operation.

In the accompanying drawings, Figure 1 is a plan view of that portion of a paper-bag machine to which I apply the printing mechanism, and includes besides said mechanism the paper-roll, the pasting appliances, and the tuber or appliance for forming the web of paper into a tube. Fig. 2 is an end elevation of the same, a part of the frame-workbeing broken away and some of the parts shown Fig. 3 is an end elevation of the printing-rolls and their adjuncts, and Figs. 4 and 5 are detail views of parts of said printing mechanism.

In the drawings, 6 represents a frame-work suitable for supporting a paper-roll and printing and pasting mechanism.

7 is the roll of paper, which is journaled upon gudgeons 8, carried by bars 9 9, extended from the frame 6.

1O 10 are tightening-rolls journaled transversely of the frame 6 andinterposed between the roll of paper and the printing mechanism. Said printing mechanism is carried upon two vertical plates 11 11, extended from the frame 6, and consists of an impression or bed cylinder 12, a type-cylinder 13, and ink-rolls 14 15. Ink is applied to the surface of the latter by a vibrating roll 16, which latter is supplied with ink by a roll1'7, secured to rotate in contact with the ink contained in an ink-welllS.

19 is a distributing-roll, which has a slight longitudinal movement upon the roll 15, whereby the ink is evenly distributed over the surface of said roll. Each of these rolls has its shaft or axle suitably journaled in the side plates 11 of the machine, and the rollers 12, 13, 14, and 15 carry spur-gears in mesh one with another. Intermittent rotary motion is imparted to the roll 17 to cause it to take up ink by means of a ratchet 20, which is engaged by a pawl 21, secured to the shaft of the roller 16. The roller 16 is given a lateral movement by means of a pitman 22,which is driven by a crank-connection with the axle of the roller 15. This roller 16 will of course be movably supported, whereby to admit of this to-and-fro movement between the rolls 15 and 17 At every revolution of the roll 15 the roller 16 will be thrown into contact with 17, and by means of the ratchet-and-pawl connection will cause the partial rotation of said roller 17. At one point of the revolution of the roll 15 the roll 16 will be brought into contact with 15 and apply the ink received from 17 to the surface of 15, upon which it will be spread by means of the endwise-movable roll 19. This movement is imparted to the roll 19 by means of a working-lever 23, pivoted at one end to abracket 24 and engaging the roll 19 at its opposite end,as indicated at 25, Figs. 1 and 4. Ato-and-fro movement is imparted to lever 23 by means ofa cam 26, secured upon the shaft of one of the train of printingrolls, said lever having a pin 27, which is engaged by said cam. A pair of supplemental ink-distributing rolls 28 29 is journaled in boxes carried by a hinged frame 30,by which they are adapted to be thrown into or out of cont-act with the printing and impression rolls, these two positions being indicated in Fig. 2 of the drawings. When thrown back into the position shown by dotted lines Fig. 2, access can be had to the printing-roll for the purpose of changing the printing-plate. Itis of first importance that the printing-rolls shall operate in perfect unison with the movement of the web of paper through the machine which forms itinto the bag, so that the impression will appear at the proper place upon the completed bag. It is not practicable to secure this result except by gearing the printing-rolls with the other operative parts of the machine, and therefore I transmit the power from the bag-machine proper to this train of rolls which do the printing.

81 represents the frame-work of the bagmachine, and 32 part of the gearing thereof, from which motion is imparted to a powershaft 33. This power-shaft carries a beveled.

gear-Wheel 34, which meshes with a similar gear 35, set upon a short shaft 36, journaled on the frame-work 6. The shaft 36 carries a gear 37, and the latter engages the spur-gear of the roller 13, whereby motion is imparted to the train of rolls. The Web of paper passes from the roll 7, about the tightening-rolls 10, and thence between the impression-roll 12 and the printing-roll 13, thence forward over tension-rolls 38 39 40. As it leaves the r011 40 it has paste applied to its margins by means of a paste-roll 41, secured to rotate in such position with relation to a paste-box 42 as to take up paste therefrom and apply it. After the paper is pasted it is then conducted over the tuber, (indicated by dotted lines in Fig. 2 at 43,) where it is formed into a tube by means of the formers 44 in the usual manner. The printing is done by means of suitable electrotype or a stereotype plate secured to the printingroll 13, and the said plate Will bear such relation in size to the size of the roll itself and the gearing will be such that the impression Will be made upon the paper at predetermined intervals and in such manner as not to interfere With the continuous travel of the web of paper.

I clain1- 1. The combination, with a bag-machine and with its primary guide-roller and Websupporting shaft, of printing mechanism ar-' ranged intermediate said roller and shaft, and suitable guide-rollers to conduct the paper from the shaft to the printing mechanism and from the printing mechanism to the primary guide-roller, substantially as described.

2. The combination, with a bag-machine and with its primary guide-roller and Websupporting shaft, of printing mechanism arranged intermediate said roller and shaft and comprising abed-roll and impression-roll bearing the printing-form and suitable inking appliances, guide-rollers to conduct the paper from the shaft to the printing mechanism and from the printing mechanism to the primary guide-roller, and a driving-shaft to impart motion to the printing-rolls, said shaft being driven by and in unison with the gearing of the bag-forming mechanism, substantially as described.
